GIA report 6552960929

2.50 ct Round Brilliant Diamond

88/100 · Refined

A strong, composed candidate on paper.

What reads well

Crown 31.5° / pavilion 41° fall outside the pairing zone associated with strong light return.
Confirm this SI1 round brilliant is eye-clean from an image or video; the report plot shows where inclusions sit.
Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.

Table · Closer look: A 60% table is larger than typical for a round brilliant (53–59%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Ideal: 60% is within the typical 59.5–63% range for a round brilliant, keeping weight where it contributes to face-up size and light return.
Crown angle · Favorable: A 31.5° crown is shallower than the typical 32–36° zone, which tends to trade some fire for brightness.
Pavilion angle · Ideal: 41° is inside the narrow 40.5–41.3° zone where the pavilion returns light most efficiently.
Polish · Ideal: Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Symmetry · Ideal: Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Girdle · Ideal: Slightly thick, faceted, 4.0%: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: None: no visible culet facet when viewed face-up.
Color · Favorable: G is near-colorless and faces up white in most settings.
Clarity · Favorable: SI1 is often eye-clean in a round brilliant, but not always — check where the inclusions sit.
Fluorescence · Ideal: Faint: no meaningful effect on appearance.
Cut grade · Ideal: Excellent as issued by GIA, on GIA's own scale. The measured proportions above tell you more than the label.

Does the large table look bright but flat, with less colored fire than you expected?
Does the feather reach the outer edge where a setting prong could put pressure on it?
Is this SI1 diamond eye-clean face-up from about 10 inches away?
Can you show me the inscribed report number under a loupe before it is set?
